Credit card pre-authorization should be cancelled in time after settlement. Will it be deducted if you don't cancel after settlement?

No, under normal circumstances, money will not be deducted. After pre-authorization, the amount will be frozen in the available limit of your credit card, occupying the available limit. If the pre-authorization transaction is not completed or cancelled, the frozen quota will be automatically unfrozen after 30 days.

For example, when you check into a hotel, you buy a pre-authorization transaction of 1000 yuan, and you spend 400 yuan when you check out. If you choose to complete the pre-authorization at this time, you will deduct the 400 yuan from the card, and the 600 yuan will be automatically unfrozen and returned to your available quota.

Generally speaking, even if the bank does not cancel the pre-authorization, the bank will automatically cancel the credit card pre-authorization after a certain period of time. However, it should be pointed out that the risk of pre-authorization transaction is actually the same as that of direct credit card consumption.

If the customer needs to cancel the order after the hotel or air ticket agent asks the cardholder to guarantee the credit card due to insufficient room rate or air ticket, but fails to handle it before the time specified by the merchant, the merchant can still withdraw the money according to the corresponding proportion of the room rate or air ticket, and the bank will not refuse to pay.
